LAM P-SHADE TRIPOD.

SPECIFICATION forming part of Letters Patent No. 444,650, dated January13, 1891.

Application filed August 28, 1890. Serial No, 363,265. m0 model.)

To all whom it may concern:

Be it known that I, AROHIBALD W. PAULL, of Wheeling, in the county ofOhio and State of Vest Virginia, have invented a new and usefulImprovement in Lamp-Shade Tripods, of which the following is a full,clear, and exact description.

My invention relates to an improveinentin tripods for supportinglamp-shades.

My invention consists in an improvement on such tripods, and is designedto afford means by which, when not in use, the tripodlegs can be movedinto the lampbowl, so that they shall not project from thelamp and shallnot make it inconvenient to pack and ship.

In the accompanying drawings, Figure 1 shows my improvement partly invertical section. Fig. 2 is a plan View of the lamp-bowl, showing thetripod-sockets; and Fig. 3 is a partial vertical sectional viewillustrating a modified arrangement of the tripod-legs.

In the drawings, 2 represents a lamp-bowl, and 4 4 are tripod-legs forupholding the shade 5. \Vith reference to the tripod-legs, my inventionconsists, broadly,- in legs set in sockets in the lamp and adapted whennot in use to be moved into the lamp-bowl from their projected anddiverging positions.

Various devices embodying my invention may be employed. I show two ofthem in the drawings.

In Fig. 1 the legs extend through slots 6 in the collar at the top ofthe lamp-bowl, andinside the lamp-bowl they are pivotally attached tolugs on a ring 7, which, when the device is used in a central-draftlamp, encircles the draft-tube 3. The legs also preferably pass throughnotches 8 in the usual flange9 in the lamp-bowl, which prevents the ringfrom being withdrawn accidentally. In order to fit the lamp forshipping, the ring 7 is dropped into the position shown by dotted linesin Fig. 1, and the legs then stand upright within the bowl. To set thelegs in position to receive the shade, they are lifted so as to draw thering 7 up into theposition shown by full lines, and are then spread andinclined so that they shall be upheld by engagement of shoulders ornotches 10 on their outer sides with the ends of the slots 6. WVhen theshade is put on the ends of the tripod-legs,its pressure will tend tospread them and will prevent them from becoming disengaged and droppingwithin the bowl. All that is necessary to do in order to drop the legsagain is to remove the shade and to move the legs sufficiently towardeach other to free the notches 10.

In Fig. 3 I show a construction in which the tripod-legs are madeseparately from each other and in which no ring 7 or other connectingdevice need be employed. In this case the slot 6 and the notches on thelegs are formed as before described; but at the lower ends of the legs Iform projections 11, and I construct on the part 9 adownwardly-projecting collar or flange 12, having lateral slots adaptedto receive the ends of the legs. When it is desired to put the tripod inposition for packing, the legs are dropped into the lampbowl through theslots 6 and the notches in the part 9, as shown by dotted lines in thedrawings. In order to adapt the legs to receive the shade, they areraised within the lamp-bowl until their notches 10 are at the slots 6,and they are then moved outwardly into inclined positions, therebycausing the notches to engage the ends of the slots and the lower endsof the legs to fit in their slots in the collar 12. When the shade isput on the legs, its spreading action holds them firmly in position, inthe manner above described with reference to Fig. 1. To place the legsback in the bowl, the shade is removed and the legs are moved intoupright positions, thereby releasing the notches 10 and their ends 11,so that the legs may be dropped freely in their sockets.

The advantages of my invention will be apparent to those having occasionto use it. The deviceis simple and inexpensive in construction, it isthe means of saving much trouble in packing and shipping the lamps, andbecause of the fact that when in condition for shipping the tripod-legsare contained within the bowl of the lamp they are not liable to be lostor injured.

I do not limit myself to constructions in l which the tripod-legs arenot removable from the lamp-bowl; but

I claim- 1. The combination, with a lamp-bowlhaw ing sockets openinginto the bowl, of shade IOO tripodlegs set in said sockets andvertically movable therein into and out of the bowl, substantially asand for the purposes described.

2. The combination, with a lamp, of tripodlegs, sockets in thelamp-bowl, in which the legs are vertically movable into and out of thebowl, and shoulders by which the legs may be upheld in projectedpositions, substantially as and for the purposes described.

3. The combination, with a lamp, of tripodlegs, a ring or frameconnecting them within the bowl, and sockets in which the legs arevertically movable into and out of the bowl,

substantially as and for the purposes described.

4:. The combination, with a lamp, of tripodlegs, a ring or frameconnecting them within the bowl, and sockets in which the legs arevertically movable into and out of the bowl, said sockets being shapedto permit divergence of the legs when projected, substantially as andfor the purposes described.

In testimony whereof I have hereunto set my hand this 26th day ofAugust, A. D. 1890.
